Answer 1

Answer:

if u like my answer mark me as a brainlist friends

Explanation:

The production of iron and carbon dioxide from iron(iii) oxide and carbon monoxide is an exothermic reaction. which expression can you use to find how many kilojoules of heat are produced when 3.40 mol fe2o3reacts with an excess of co?fe2o3( s) + 3co( g) → 2fe( s) + 3co2( g) + 26.3 kj.

Answer 2

This is an incomplete question, here is a complete question.

The production of iron and carbon dioxide from iron oxide and carbon monoxide is an exothermic reaction. which expression can you use to find how many kilojoules of heat are produced when 3.40 mol Fe₂O₃ reacts with an excess of CO?  ΔH = +26.3 kJ

The amount of heat produced will be, 89.4 kJ

Explanation :

The chemical reaction will be:

$Fe_2O_3+3CO\rightarrow 2Fe+3CO_2$

From the balanced chemical reaction, we conclude that:

As, the amount of heat produced from 1 mole of $Fe_2O_3$ = 26.3 kJ

So, the amount of heat produced from 3.40 mole of $Fe_2O_3$ = 3.40 × 26.3 kJ = 89.4 kJ

Therefore, the amount of heat produced will be, 89.4 kJ
